The first civilian trial of a former Guantánamo Bay prisoner has been delayed after a federal judge ruled prosecutors can’t call a key witness to the stand. The prisoner, Ahmed Ghailani, has pleaded not guilty on charges surrounding the 1998 embassy bombings in East Africa that killed 224 people. On Wednesday, District Judge Lewis Kaplan barred a Tanzanian man who says he sold weapons to Ghailani on the grounds he was tracked down as a result of Ghailani’s coerced statements under CIA interrogation. Defense attorney Peter Quijano praised the decision.

Peter Quijano: “Judge Kaplan ruled today that the Constitution is the rock upon which our nation rests. We could not agree more with the court. This case will be tried upon lawful evidence, not torture, not coercion. It is the Constitution that won a great victory today. We applaud the court for its courage and support for the law.”
